The weirdest games in the world

A free Japanese game with retro graphics, Yume Nikki (PC; 2005) tells the story of a teenage girl who never ventures out of her room, and who has the most disturbing of dreams. These nightmares make up what can be loosely referred to as the game’s levels, and in them you’ll search large, confusing spaces for various special abilities. The central story is only hinted at until the final moments, but there’s plenty of obscure symbolism going on in the meantime. Despite being as strange as games get, this one’s gained itself a loyal cult fanbase who debate its intricacies across the Internet.
